Abstract: the main purpose of this experiment is build real time system using PPI 8255 to control devices connected to. Problem description: assume that there are two devices are connected to port A and two sensors are connected to port B of PPI 8255. They work according to the following table Sensors (S1S2) Devices (DID2) 00 01 01 10 10 11 11 00 Write a program to control these two devices according to the values of sensors.

Create a program that changes the color of the RGB LED using the detected ambient light intensity using a light-dependent resistor (LDR).

You have 1000 bottles of soda, and exactly one is poisoned. You have 10 test strips whichcan be used to detect poison. A single drop of poison will turn the test strip positive permanently.You can put any number of drops on a test strip at once and you can reuse a test strip as many timesas you'd like (as long as the results are negative). However, you can only run tests once per day andit takes seven days to return a result. How would you figure out the poisoned bottle in as few daysas possible?Follow up: Write code to simulate your approach

Write a program that lights an LED attached to pin 3. The LED should turn off after a button attached to pin 4 has been pushed 3 times. Assume the button is wired active low. Assume there is least 1/4 second between button presses.

Use all the logic operators discussed previously to darken an image only within a region of interest. Would pixel-by-pixel division be a better way to find the differences between two monochrome images than subtraction, absolute difference, or XOR? Explain.

For this milestone, you will be making a more complicated pattern in each cell. You will be splitting the cell into several shapes and individually filling/coloring them in.  You can still: decide whether the cells and its patterns are filled or unfilled choose the fill and pen colors using the user inputs Like the previous milestone, you will be asking for the fill colors for each individual shape/section as well. Sample output: Grid size (n): (input) Pen color: (input) Fill color: (input) Rectangle color: (input) Triangle color: (input) Each cell should have this drawing. The specific of this drawing is: A rectangle with a width 1/4 of the cell width and height the same as the cell Two triangles created by a diagonal line starting from the top right corner of the rectangle and ending on the bottom right of the cell  You can simplify drawing the triangles by only drawing and filling in one of them, leaving the other as part of the cell background Here is a full grid with the cell…

METHOD: Put on gloves and place one piece of bread in a re-sealable plastic bag using a gloved hand. Label this first bag “controlled”.  QUESTION: What will be the result and write your conclusion

The code is not working can you recode it?

We have three push button, When the first push button is pressed, the LED is on continuously and when the second push button is pressed, the LED turns on and off, and the last switch turns off the LED program by use arduino

Write a program that turns on an LED attached to pin 3 for 5 seconds then turns it off. The light should stay off for 3 seconds and then the LED should blink 10 times at a rate of 1 Hz (on and off each second). in TinkerCAD with Code
